ABSTRACT:
A medium for determining Escherichia coli sensitivity to a pre-selected antimicrobial agent. The medium contains nutrient sources, inhibitors to inhibit growth of gram-positive and of other gram-negative micro-organisms, and an indicator which will show metabolic activity or lack thereof by E. coli in the medium, and a specific antimicrobial agent whose effectiveness against E. coli is being tested. If a given agent is effective against E. coli when E. coli is added to the medium containing that agent, the medium will remain clear. If the specific agent is ineffective against E. coli the color of the medium containing E. coli and that agent will change to blue as the E. coli metabolizes in the medium and produces acid.
